SELF-DRYING PAD FOR PRESSING MACHINES.

application filed .Tune 10, 1926. Serial 110.115,064.

This invention relates'to pressing machines of the type used in laundries, and has for its object a padding for the buck of, the maincludes a stationary buck 1, mounted on a shine', which padding is self-drying and also dries or tends to dry the article being pressed;

4The invention consists in the novel fea-l tures, and inthe combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters represent corresponding parts in all the views.y

Figures 1`an'd. 2 arev fragmentary side elevations, partly in section, of a pressing machine embodying my'invention, the machine being shown as open in Figure l, and as closed with the air chamber compressed in Figure 2;

The machine may be of any suitable form, size and construction and that here shown bracket or goose neck 2, which in turn is mounted upon the tableor frame 3 .of the machine, and a head 4 movable toward and from the buck 1 andcarried by a yoke or lever 5, pivoted between lits ends at 6 to a frame 7 rising from the frame.

The yoke 5 is actuated inv any suitable manner either b y hand, foot or power as will be understood by those skilled in the art.

The buck 1 is formed with an internal chamber 8 for receiving a heating medium as steam. Various ,forms of pads and spring pads have been uesd in pressing machines and these may to some extent act incidentally to create 'a suction throug the pad, but such suction has only been incientally and never been utilized, at least to such an extent as to be effective and certain.

9 designates an air chamber having a metal bottom wall 10 and metal corrugated sideand'end walls '11 in the forni of a bellows,

the inner margins of the metal side and end' walls being provided with a lip at 12, which l.fits the buck.

13 is the top wall of the air chamber, this being iiexible. usually formed of a porous layer of fabric land also a foraminous v nates a check valve controlling the inflow of air into the interior of the pad through the passage 17 in the buck, the passage opening into the outer air. The check valve is shown as of the flap type and as pressed toward its seatin any suitable manner as by its own resiliency and the pressure within the pad when compressed. When the pad is compressed by the head 4, the valve4 closes by the natural resiliency of the material of which it is formed and by the pressure of the air in the pad during the compression ofthe pad, as. the side walls or bellows 11 of the pad are impervious andthe How of air through the lpervious top wall is preventedby the yhead later, when the air is no longer compressed, l

the outer air rushes in through'the passage.

17 past the flap valve.

Owing to the corrugated or bellows walls l1, the air chamber can be made to displace a large amount of heated air through its upper wall when being compressed. This air is heated within the chamber and therefore owing to the check valve controlled inlet a large, volume ot relatively cooler air is- .drawn in through the inlet, and expands in the chamber to a f lgreater volumel and thus when the machine is open is constantly forcing 1tself out through the porous top to dry the padding, and also dries the garment or other article thereon while the airis being driven out through-the top Walls of the chamberduring the compression of the air chamber., The metal walls and springs serve to conduct and distribute the heat through the large body of air, so that the air is quickly heated.

` Thus the air chamber padding is kept dry by means self-contained with the padding, and also the garment is dried out to a great extent.

f What I'claim is 1. In a pressing machine the combination with a buck and a head movable toward and vfrom the buck of a compressible and expansible air chamber mounted on the buck and arranged to be compressed by the pressure of the head thereon, the chamber having a check Valve cont-rolled air inlet and having its upper wall, which is opposed to the head,

'ItI

porous, providing an outlet for the air during the compression of the chamber.l

2. In a'pressing machine the combination with a buck and a head movable toward and from the buck of a compressible and expansible air chamber mounted on-.the buck, and arranged to be compressed by the pressure of the head thereon, the chamber having a check valve controlled air inlet and having its upperwall, which is opposed to the head, porous, providing an outlet for the air during the compression of the chamber, and means for heating the air in said chamber.

. 3. In a pressing-machine the combination with Aa heated buck, and a head movable toward and from the buck, of an air chamber mounted on the buck and having metal heat conducting walls contiguous with the buck, the side and end walls of the chamber being inthe form of a bellows whereby the cham? ber is exp'ansible and compressible, the top wall of the chamber being porous and the 'chamber having a check valve controlled air inlet.

4. In a' pressing m'achine the combination -with a heated buck, and a. head movable toward and from the buck, of an air lchamber mounted on the buck and having metal heat conducting Walls contiguous with the buck, theslde and end walls of t-he chamber being in the form of bellows whereby the chamberu is expansible and compressible, the top wall being porous and a plurality of compressible springs between the top and bottom walls,

and including air tight side and bottom walls, and a porous 'top`wall, the chamber having a check valve controlled air inlet.

6. Ina' pressing machine the combination with a buck and a head movable toward and from the buck, a compressible and expansible air chamber mounted on the buckand including air tight heat conducting side'and bottom walls, and a porous top Wall, the chamber having a cheek valve controlled air inlet, and springs interposed between the to and .bottom Walls of the air chamber.

gf In a pressing machine the combination of a heated buck, ahead movable toward and from the buck, a compressible and expansible air chamber mounted on the buck and incl lding metal heat conducting bottom and sid lWalls, and a flexible porous top wall, the side walls beine' compressible and heat conducting springs etween the bottom and'top walls, the air chamber having a lcheck valve controlled air inlet."

In testimony whereof, I have hereunto Y signed my name at Syracuse, in the county Aot' Onondaga, and in the State of New York,

this 29th day of May, 1926.
